Become a crime scene investigator! Learners model Dawn Mission scientists, engineers, and technologists and how they use instrumentation to detect distant worlds. After a briefing to build context, students explore interactions between different...(View More) frequencies/wavelengths of the electromagnetic spectrum and matter as they investigate the different ways scientists gather and understand remote sensing data, using Dawn instruments as examples. This module is organized around a learning cycle, engaging students through several experiences to activate students' prior knowledge and assess conceptual understanding, informing next steps.(View Less)

Learners will investigate various ways to improve mission design to maximize the scientific return. In the first activity, students examine how the use of flowcharts can help make computer programs error-free and efficient, in this way making the...(View More) spacecraft more reliable. In the second activity, the students investigate how data can be compressed for transmission over limited bandwidth. By the end of the lesson, the students come to realize that the wealth of data gathered by spacecraft is useless if it cannot be transmitted safely and efficiently to scientists on Earth. Note: The MESSENGER mission to Mercury that is mentioned in this lesson ended operations April 30, 2015.
